Abstract

The invention relates to a cutting device (1) for cutting hair, having at least two blades (2, 3) which move back and forth relative to each other. The blades (2, 3) are provided with teeth (8, 9) which extend transversally to the direction of movement (P), and tooth gaps (25, 26) arranged therein. The teeth (8, 9) have contact surfaces (4, 5) on their facing sections which are in gliding contact with each other and which form cutting edges (34, 35) on their sides bounding the tooth gaps (25, 26) such that the back and forth movement (P) of the blades causes the tooth gaps (25, 26), cooperating with each other, to form constantly changing cutting gaps (32) in which hair becomes clamped and is finally cut. According to the invention, the free ends of teeth (9) of one blade (3) project over sections (15) of free ends of teeth (9) of other blades (2), and projections (17) extend from the projecting sections (15) of the teeth (9) on the contact surfaces (5) side. The projections (17) improve the cutting result by erecting the hairs lying flat against the skin surface (29) during the cutting process, feeding them more easily to the teeth (8, 9).

Description

Schneideinrichtung zum Schneiden von Haaren Cutting device for cutting hair
Die Erfindung betrifft eine Schneideinrichtung zum Schneiden von Haaren gemäß dem O- berbegriff des Patentanspruchs 1.The invention relates to a cutting device for cutting hair according to the term of claim 1 O.
Sowohl aus der EP 1 140 437 B1 wie aus der DE 26 46 818 A sind bereits derartige Schneideinrichtungen bekannt. Dabei gleiten die Kontaktflächen der beiden Klingen derart gegeneinander, daß bei der Hin- und Herbewegung (P) in die Zahnlücken der Zähne gelangende Haare von den an den Übergängen der Kontaktflächen zu den Seitenflächen der Zähne ausgebildeten Schneidkanten eingeklemmt und anschließend abgeschert bzw. abgeschnitten werden. Die durch die gegenüberliegenden Zähne gebildeten Schneidspalte werden entsprechend der Hin- und Herbewegung der Klingen ständig vergrößert und wieder verkleinert bzw. sogar völlig verschlossen, um über die ganze Länge einer Schneidkante die Haare erfassen und abschneiden zu können. Bei beiden oben erwähnten Schneideinrichtungen sind die Zähne des einen Messers länger als die Zähne des anderen Messers, so daß die Kammenden des einen Messers über die Kammenden des anderen Messers nach vorne hinausragen.Both from EP 1 140 437 B1 and from DE 26 46 818 A such cutting devices are already known. In this case, the contact surfaces of the two blades slide against each other so that in the reciprocating motion (P) in the tooth gaps of the teeth reaching hair trapped by the formed at the transitions of the contact surfaces to the side surfaces of the teeth cutting edges and then sheared or cut off. The cutting gaps formed by the opposing teeth are constantly increased in accordance with the reciprocating motion of the blades and again reduced or even completely closed to capture and cut the hair over the entire length of a cutting edge can. In both cutting devices mentioned above, the teeth of one blade are longer than the teeth of the other blade so that the comb ends of one blade protrude beyond the comb edges of the other blade.
Aus der DE 103 44 566 A1 ist weiterhin ein Schersystem bekannt, bei dem der aus einem Ober- und Untermesser bestehenden Schneideinrichtung eine Zuführvorrichtung vorgelagert ist, die relativ zum Obermesser oszillierend hin- und herbewegt wird. Mit der Zuführvorrichtung soll einerseits eine möglichst gründliche und hautschonende Haarentfernung möglich sein und andererseits sollen insbesondere auch lange und/oder eng an der Haut anliegende Haare mit einer vergleichsweise hohen Wahrscheinlichkeit vom Schersystem erfaßt und entfernt werden. Bei dieser Ausführungsform bildet die Zuführvorrichtung eine vom Antriebssystem zusätzlich hin- und herbewegte Einheit, die der eigentlichen Schneideinrichtung vorgestellt ist.From DE 103 44 566 A1, a shearing system is furthermore known, in which the cutting device consisting of an upper and lower knife is preceded by a feeding device which is oscillated back and forth in an oscillating manner relative to the upper knife. With the delivery device on the one hand the most thorough and gentle hair removal should be possible on the one hand and on the other hand, especially long and / or closely fitting to the skin hair should be detected and removed with a relatively high probability of the shear system. In this embodiment, the feeder forms an additional reciprocating unit from the drive system which is presented to the actual cutter.
Schließlich ist noch aus der DE 10 2005 002 895 A1 ein elektrisches Haarschneidegerät bekannt, bei dem die Außenfläche des Obermessers eines Mittelschneiders erhabene Bereiche aufweist, die während eines Rasiervorganges den Kontakt zur Hautoberfläche einer Bedienungsperson herstellen. Durch die erhabenen Bereiche sollen beim Rasiervorgang auch die eng an der Haut anliegenden längeren Haare möglichst zuverlässig erfaßt und vom Mittelschneider durchtrennt werden. Aufgabe der Erfindung ist es nun, eine Schneideinrichtung zu schaffen, bei der mit besonders einfachen Mitteln auch eng an der Haut anliegende Haare besser von den Zähnen erfaßt, in die Zahnlücken eingefädelt und schließlich von der Schneideinrichtung abgeschnitten werden.Finally, from DE 10 2005 002 895 A1 an electric hair trimmer is known, in which the outer surface of the upper blade of a central cutter has raised areas, which make contact with the skin surface of an operator during a shaving operation. Due to the raised areas, the longer hair, which fits tightly against the skin, should also be reliably detected during the shaving process and severed by the central cutter. The object of the invention is therefore to provide a cutting device, in which with particularly simple means also closely fitting to the skin of hair caught by the teeth, threaded into the tooth spaces and finally cut off from the cutting device.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Dadurch, daß auf der Seite der Kontaktflächen an den überstehenden Abschnitten der Zähne der einen Klinge Vorsprünge ausgebildet sind, sind diese den Zähnen der anderen Klinge vorangestellt bzw. vorgelagert. Beim Rasiervorgang, also bei der Bewegung, bei der die unrasierte Haut zunächst erst gegen die Spitzen der längeren Zähne gerät, werden durch die Vorsprünge die Haare besser erfaßt, aufgerichtet und leichter den Schneidspalten zugeführt, was zu einem besseren Rasierergebnis führt. Da durch die Vorsprünge die Spitzen der dahinter liegenden Zähne der anderen Klinge mehr geschützt sind, werden sie auch weniger in Kontakt mit der Hautoberfläche gebracht, was eine die Haut mehr schonende Rasur ergibt. Durch die Erfindung bedarf es keiner zusätzlichen Bauteile, wie Umlenkhebel oder Achsen, was den Fertigungsaufwand reduziert.This object is achieved by the characterizing features of claim 1. Characterized in that on the side of the contact surfaces on the protruding portions of the teeth of a blade projections are formed, these are the teeth of the other blade preceded or upstream. When shaving, so in the movement in which the unshaved skin first against the tips of the longer teeth, the hair is better detected by the projections, erect and easier fed to the cutting gaps, resulting in a better shaving result. Since the projections of the tips of the underlying teeth of the other blade are more protected, they are also less brought into contact with the skin surface, resulting in a skin more gentle shave. The invention requires no additional components, such as lever or axles, which reduces the production cost.
Durch die Erfindung können die Kanten an den Zähnen der anderen, nachgestellten Klinge scharfkantig ausgebildet sein. Scharfkantige Klingen verbessern nämlich das Aufrichten und Einfädeln der Haare in die Schneidspalte, würden aber die Hautoberfläche stärker strapazieren, wenn nicht erfindungsgemäß den nachgestellten Zahnspitzen die Vorsprünge vorgelagert wären. Dadurch ergibt sich also ein besseres Rasierergebnis bei größerer Hautschonung.By the invention, the edges on the teeth of the other, re-adjusted blade can be sharp-edged. Sharp-edged blades improve the erection and threading of the hair into the cutting gap, but would stress the surface of the skin more if not according to the invention, the protrusions would be located upstream of the trailing tooth tips. This results in a better shaving result with greater skin protection.
Die Klingenbewegung richtet sich zweckmäßigerweise nach der Außenkontur der Verzahnung und kann daher geradlinig, bogen- oder kreisförmig sein.The blade movement expediently depends on the outer contour of the toothing and can therefore be rectilinear, curved or circular.
Gemäß den Merkmalen des Patentanspruchs 2 ist die mit den Vorsprüngen versehene Klinge mit der oszillierenden Hin- und Herbewegung beaufschlagt, was das Einfädeln der Haare in die Schneidspalte weiter begünstigt. Dabei bildet die andere Klinge den feingliedrigen Kamm, während die mit den Vorsprüngen versehene Klinge das eigentliche Messer der Schneideinrichtung bildet. Beim Rasiervorgang werden also durch die Hin- und Herbewegung der Vorsprünge die Haare von diesen aufgerichtet und den Zahnlücken der anderen Klinge, nämlich dem feingliedrigen Kamm, zugeführt, wo sie letztendlich dann ausgerichtet, zwischen den Zähnen eingeklemmt und abgeschnitten werden. Die Vorsprünge sind rundum verrundet und schützen so die Haut vor den scharfen Kanten der anderen, dahinter liegen- den Klinge, nämlich dem Kamm. Die sich auf der Haut bewegenden Vorsprünge könnten durch spezielle Gestaltung gezielt zum Peeling oder Lockerung der Haare im Haarkanal verwendet werden. Untersuchungen mit der erfindungsgemäßen Ausgestaltung haben gezeigt, daß durch die Vorsprünge das Lockern der Haare verbessert und dadurch eben die Gründlichkeit der Rasur erhöht wird.According to the features of claim 2, the blade provided with the projections is acted upon by the oscillating reciprocating movement, which further promotes the threading of the hair in the cutting gaps. In this case, the other blade forms the slender comb, while the blade provided with the projections forms the actual knife of the cutting device. During the shaving process, the hairs are erected by the reciprocating motion of the projections and the tooth gaps of the other blade, namely the slender comb, fed, where they are then finally aligned, clamped between the teeth and cut off. The projections are rounded all around and protect the skin from the sharp edges of the others, behind it. the blade, namely the comb. The moving on the skin projections could be used by special design targeted for exfoliation or loosening of the hair in the hair channel. Studies with the embodiment of the invention have shown that the loosening of the hair improved by the projections and thus just the thoroughness of the shave is increased.
Gemäß den Merkmalen des Patentanspruches 3 werden die Vorsprünge von in ihrer Längsrichtung zapfen- , stift- oder säulenförmig ausgebildeten Erhebungen gebildet, deren nach außen zeigende Seitenwand stufenlos in die Seitenflächen des jeweiligen Zahnes übergeht. Die Seitenwand eines Vorsprunges geht also eben geradlinig in die Seitenfläche eines Zahnes über und bildet mit dem jeweiligen Zahn gemeinsam eine verlängerte Spitze. Der Querschnitt eines Vorsprunges kann kreisförmig, oval, mehreckig oder sonst wie ausgebildet sein, wichtig ist nur, daß beim Rasiervorgang die Hautoberfläche auf einen zur Spitze gerundeten Vorsprung trifft, um nicht verletzt zu werden. Die Querschnitte der Vorsprünge sowie die Zahnspitzen des Messers können auch zu den Rändern der Klingen hin stumpfer werden, um eine größtmögliche Hautschonung zu bewirken. Die Vorsprünge können auch als gerundete Noppen ausgebildet sein.According to the features of claim 3, the projections are formed in their longitudinal direction pin, pin or columnar elevations formed, the outwardly facing side wall passes smoothly into the side surfaces of the respective tooth. The side wall of a projection thus goes straight into the side surface of a tooth and forms an extended tip together with the respective tooth. The cross section of a projection may be circular, oval, polygonal or otherwise formed, it is only important that during shaving the skin surface meets a rounded to the tip projection so as not to be injured. The cross-sections of the projections as well as the tips of the teeth of the knife may also become blunt towards the edges of the blades to effect the greatest possible skin protection. The projections may also be formed as rounded nubs.
Nach den Merkmalen des Patentanspruchs 4 bildet die mit der Seitenfläche eines Zahnes abschließende Mantelfläche eines Vorsprungs mit der Seitenfläche des jeweiligen Zahnes eine gemeinsame Ebene. Dadurch werden stufige Übergänge von den Vorsprüngen zu den Seitenflächen der Zähne an den nach außen weisenden Bereichen vermieden, was beim Rasiervorgang die Oberfläche der Haut einer Bedienungsperson besser schont.According to the features of claim 4 forms the final with the side surface of a tooth lateral surface of a projection with the side surface of the respective tooth a common plane. This avoids step transitions from the projections to the side surfaces of the teeth at the outwardly facing portions, which better protects the surface of an operator's skin during shaving.
Gemäß den Merkmalen des Patentanspruchs 5 verjüngt sich die Seitenwand eines Vorsprunges zu seinem freien Ende hin. Dies ermöglicht eine einfachere Herstellung der Klinge, die vorzugsweise im Präge-Stanz-Verfahren hergestellt wird. Dabei werden vorzugsweise beim Prägevorgang die Vorsprünge aus der Ebene der Zähne nach oben heraus geformt. Anschließend werden die Zähne ausgestanzt oder mit einem Laserstrahl ausgeschnitten.According to the features of claim 5, the side wall of a projection tapers towards its free end. This allows a simpler manufacture of the blade, which is preferably produced in the embossing-punching process. In this case, the protrusions are preferably formed out of the plane of the teeth upwards during the embossing process. Then the teeth are punched out or cut out with a laser beam.
Nach den Merkmalen des Patentanspruches 6 sind die Vorsprünge an ihren Stirnseiten mit nach außen gewölbten Endabschnitten versehen. Durch die nach außen gerundeten freien Enden der Vorsprünge wird somit beim Rasiervorgang die Haut besser geschont.According to the features of claim 6, the projections are provided at their end faces with outwardly curved end portions. By rounded outward free ends of the projections thus the skin is better protected during shaving.
Gemäß den Merkmalen des Patentanspruchs 7 wird die erfindungsgemäße Schneideinrichtung als Trimmer oder Konturenschneider verwendet, d.h., die an den Spitzen der Zähne ausgebildeten Seitenflächen bilden die Gleitfläche gegenüber der Hautoberfläche einer Bedienungsperson. Derartige senkrecht ausgestellte Trimmer sind in der Regel an der Vorderseite eines Rasierergehäuses angebracht, wie dies beispielsweise bei dem von der Anmelderin vertriebenen „Braun Synchro" der Fall ist. Der Trimmer kann aber auch beispielsweise zu seinem Gebrauch aus der Seitenwand eines Rasiererghäuses senkrecht herausgeklappt werden. Die erfindungsgemäße Schneideinrichtung kann aber auch an einem Gerät, das als Bartschneider Verwendung findet, ausgebildet sein.According to the features of claim 7, the cutting device according to the invention is used as a trimmer or contour cutter, ie, at the tips of the teeth formed side surfaces form the sliding surface against the skin surface of an operator. Such vertically deployed trimmers are typically mounted on the front of a razor housing, such as the "Braun Synchro" sold by the Applicant, but the trimmer may also be folded vertically out of the sidewall of a razor housing, for example. The cutting device according to the invention can also be formed on a device that is used as a beard trimmer.
Nach den Merkmalen des Patentanspruches 8 bildet diejenige Klinge, an der nicht die Vorsprünge ausgebildet sind, die Kontaktfläche zur Hautoberfläche, d.h., beim Rasiervorgang gleitet die Außenfläche des feingliedrigen Kammes an der Hautoberfläche entlang und bildet somit in dieser Ausführungsform das Obermesser, während die mit den Vorsprüngen versehene Klinge das Untermesser bildet, das vorzugsweise oszillierend hin- und herbewegt werden kann. Gemäß den Merkmalen des Patentanspruchs 9 ist die Schneideinrichtung einem Kurzhaarschneidesystem vor- bzw. nachgelagert ist, d.h., in der einen Bewegung ergreift zunächst die Schneideinrichtung nach der Erfindung die längeren Haare, während anschließend der Feinschnitt durch das nachgelagerte Kurzhaarschneidesystem (bestehend aus perforierter Folie und einem hin und hergehenden Untermesser) erfolgt.According to the features of claim 8, that blade on which the protrusions are not formed, the contact surface to the skin surface, ie, during shaving the outer surface of the slender comb slides along the skin surface and thus forms the upper blade in this embodiment, while with the Protruding blade forms the lower blade, which can preferably oscillating reciprocated. According to the features of claim 9, the cutting device is a short-hair cutting system upstream or downstream, ie, in one movement first engages the cutting device according to the invention, the longer hair, while then the fine cut by the downstream Kurzhaarschneidesystem (consisting of perforated film and a back and forth lower knife) takes place.
In einer anderen Ausführungsform gemäß den Merkmalen des Patentanspruches 9 bildet die erfindungsgemäße Schneideinrichtung einen Mittelschneider, der zwischen zwei Kurzhaarschneidesystemen zwischengelagert ist. Dabei weist die erfindungsgemäße Schneideinrichtung zu beiden Seiten hin frei auslaufende Zähne auf, wobei an der sich hin- und herbewegenden Klinge an den Enden der Zähne die Vorsprünge nach oben zum Kamm ragen. Dadurch sind die Zähne der mit der Haut in Kontakt bringbaren Klinge beim Rasiervorgang in beiden Rasierrichtungen von den Vorsprüngen geschützt nachgelagert. Ein Mittelschneider ohne den Erfindungsgegenstand ist beispielsweise durch den von der Anmelderin seit längerem vertriebenen Rasierer Braun "360° Complete" oder den Rasierer Braun "Pulsonic" bekannt. Bei diesen Rasierertypen könnte anstelle des dort bekannten Mittelschneiders die erfindungsgemäße Schneideinrichtung eingesetzt werden.In another embodiment according to the features of claim 9, the cutting device according to the invention forms a central cutter, which is interposed between two Kurzhaarschneidesystemen. In this case, the cutting device according to the invention on both sides towards freely expiring teeth, wherein protrude at the reciprocating blade at the ends of the teeth, the projections up to the comb. As a result, the teeth of the blade, which can be brought into contact with the skin, are stored downstream of the projections during the shaving process in both directions of shaving. A center cutter without the subject invention is known, for example, by the razor Braun "360 ° Complete" or the razor Braun "Pulsonic", which has long been marketed by the applicant. In these razor types, the cutting device according to the invention could be used instead of the middle cutter known there.

Fig. 1 eine perspektivische Draufsicht von rechts oben auf ein Ausführungsbeispiel der erfindungsgemäßen Schneideinrichtung in vergrößertem Maßstab, Fig. 2 einen Schnitt durch die Schneideinrichtung gemäß der Schnittführung l-l nach Fig. 1 in noch größerer Darstellung und1 is a perspective top view from the top right of an embodiment of the cutting device according to the invention on an enlarged scale, Fig. 2 shows a section through the cutting device according to the cutting guide ll of FIG. 1 in even greater illustration and
Fig. 3 eine gegenüber Figur 1 vergrößerte Darstellung des Ausschnittes X nach Fig. 1.FIG. 3 is an enlarged view of the detail X of FIG. 1 as compared to FIG. 1.
In den Figuren 1 bis 3 besteht die Schneideinrichtung 1 aus einer oberen Klinge 2 und einer unteren Klinge 3, die über aufeinander gleitende Kontaktflächen 4, 5 (Fig. 2) in Gleitkontakt stehen. An den vorderen freien Enden 6, 7 der oberen und unteren Klinge 2, 3 sind nach den Figuren 1 und 3 kammartig ausgebildete Zähne 8, 9 in Zahnreihen 27, 28 angeordnet, deren Spitzen 10, 1 1 auf geraden, parallel zueinander verlaufenden Linien, 36, 12 (hier strichpunktiert dargestellt) liegen. Der Zahngrund 13 aller Zähne 8, 9 liegt auf der geraden Linie 37 (untere Linie nicht erkennbar), wobei alle Linien 36, 12, 37 vorzugsweise parallel zueinander verlaufen.In FIGS. 1 to 3, the cutting device 1 consists of an upper blade 2 and a lower blade 3, which are in sliding contact via sliding contact surfaces 4, 5 (FIG. 2). At the front free ends 6, 7 of the upper and lower blades 2, 3 comb-like teeth 8, 9 are arranged in rows of teeth 27, 28 according to Figures 1 and 3, the tips 10, 1 1 on straight lines parallel to each other, 36, 12 (shown in phantom) lie. The tooth base 13 of all teeth 8, 9 lies on the straight line 37 (lower line not visible), wherein all the lines 36, 12, 37 are preferably parallel to each other.
Die obere Klinge 2 bildet nach den Figuren 1 bis 3 in diesem Ausführungsbeispiel den eigentlichen Kamm der Schneideinrichtung 1 , während die untere Klinge 3 das Messer bildet. Vorzugsweise kann daher nur das Messer 3 in den Richtungen P oszillierend hin- und herbewegt werden, wobei die Bewegung P vorzugsweise senkrecht bzw. quer zu der Erstreckung der Zähne 8, 9 bzw. parallel zu der Linie 12 verläuft. In diesem Ausführungsbeispiel ist entweder an dem Messer 3 angekoppelt oder in diesem integriert ein mit einem Antriebsteil (nicht dargestellt) eines Elektromotors (nicht dargestellt) verbindbares Kupplungselement 14 angeordnet, über das das Messer 3 in die hin- und hergehende Schwingungen P versetzt wird. Weiterhin ist eine in der Zeichnung nicht dargestellte Andrückvorrichtung, vorzugsweise eine oder mehrere Federn, in der Schneideinrichtung 1 ausgebildet, durch die das Messer 3 mit seiner Kontaktfläche 5 gegen die Kontaktfläche 4 des Obermessers 2 gedrückt wird.The upper blade 2 forms according to Figures 1 to 3 in this embodiment, the actual comb of the cutting device 1, while the lower blade 3 forms the knife. Preferably, therefore, only the knife 3 can be reciprocated in the directions P oscillating, wherein the movement P is preferably perpendicular or transverse to the extension of the teeth 8, 9 and parallel to the line 12. In this embodiment, either coupled to the blade 3 or integrated therein with a drive part (not shown) of an electric motor (not shown) connectable coupling element 14 is arranged, via which the blade 3 is set in the reciprocating vibrations P. Furthermore, a pressing device, not shown in the drawing, preferably one or more springs, formed in the cutting device 1, through which the blade 3 is pressed with its contact surface 5 against the contact surface 4 of the upper blade 2.
Wie weiterhin aus den Figuren 1 bis 3 hervorgeht, erstrecken sich die Zähne 9 der unteren Klinge 3 über die Zähne 10 der oberen Klinge 2 nach vorne über den Abschnitt 15 hinaus. Dies kann einerseits dadurch erreicht werden, daß die unteren Zähne 9 länger sind als die oberen Zähne 8 oder andererseits dadurch, daß alle Zähne 8, 9 gleich lang sind, jedoch gegeneinander um das Maß (a) versetzt sind.Still referring to FIGS. 1-3, the teeth 9 of the lower blade 3 extend beyond the teeth 15 of the upper blade 2 forward beyond the portion 15. This can be achieved on the one hand by the fact that the lower teeth 9 are longer than the upper teeth 8 or on the other hand in that all the teeth 8, 9 are the same length, but offset from each other by the measure (a).
Von der Oberfläche 16 des Messers 3, die vorzugsweise auf gleicher Höhe wie die Kontaktfläche 5 liegt, erstreckt sich nach den Figuren 1 bis 3 je ein Vorsprung 17, Die Vorsprünge 17 schützen die benachbarten Spitzen 10 der Zähne 8 der oberen Klinge 2, wenn die Hautoberfläche 29 beim Rasiervorgang in Richtung B2 gegen die Zahnspitzen 11 gedrückt wird. Die Vorsprünge 17 sind vorzugsweise stift- bzw. säulenförmig ausgebildet und weisen an ihren freien Enden konvex (nach oben) gewölbte Endabschnitte 18 in Form von Kappen auf, die mit den Oberseiten 21 der Zahnspitzen 10 vorzugsweise fluchten, geringfügig darüber oder auch darunter verlaufen können. Die Vorsprünge 17 bilden umfangsseitig eine Mantelfläche 19, die ohne Stufe (Fig. 2 und 3), also geradlinig in die Seitenflächen 20 der Abschnitte 15 einlaufen, d.h., hier entstehen keine Stufen. Nur dort, wo die Mantelfläche 19 auf die Oberfläche 16 trifft entsteht zwangsweise eine Ecke 38; diese liegt aber geschützt im Innenbereich an den Zähnen 9. Zwischen den Vorsprüngen 17 und den Zahnspitzen 10 ist ein geringer Spalt 22 vorhanden, damit sich die Klingen 2, 3 in diesem Bereich ungehindert gegeneinander bewegen können.From the surface 16 of the blade 3, which is preferably at the same height as the contact surface 5, extends according to the figures 1 to 3 depending on a projection 17, the projections 17 protect the adjacent tips 10 of the teeth 8 of the upper blade 2 when the skin surface 29 is pressed against the tooth tips 11 during shaving in the direction B2. The projections 17 are preferably pin-shaped or column-shaped and have at their free ends convexly (upward) arched end portions 18 in the form of caps, which are preferably aligned with the tops 21 of the tooth tips 10, slightly above or below. The projections 17 form on the circumference a lateral surface 19, which run without a step (FIGS. 2 and 3), ie in a straight line into the side surfaces 20 of the sections 15, ie no steps are formed here. Only where the lateral surface 19 meets the surface 16 forcibly creates a corner 38; but this is protected in the interior of the teeth 9. Between the projections 17 and the tooth tips 10, a small gap 22 is present so that the blades 2, 3 can move freely in this area against each other.
Nach den Figuren 1 und 2 ist die obere Klinge 2 im hinteren Bereich über das Endstück 23 etwa 90° abgewinkelt, um das Obermesser 2 im Rasierergehäuse (nicht dargestellt) zu befestigen. Die Schneideinrichtung 1 gemäß den Figuren 1 bis 3 kann auch vorzugsweise als Trimmer eingesetzt werden, wobei sie dann vorzugsweise an der Vorderseite eines Rasierergehäuses (nicht dargestellt) hervorsteht und senkrecht von vorne gegen die Spitzen 10, 11 an die zu rasierende Hautoberfläche 24 geführt wird. Die Rasierbewegung verläuft dann in Richtung C hin und her.According to Figures 1 and 2, the upper blade 2 is angled in the rear over the end piece 23 about 90 °, to secure the upper blade 2 in the shaver housing (not shown). The cutting device 1 according to FIGS. 1 to 3 can also preferably be used as a trimmer, wherein it preferably protrudes (not shown) on the front side of a razor housing and is guided perpendicularly from the front against the tips 10, 11 against the skin surface 24 to be shaved. The shaving movement then goes back and forth in direction C.
Da die Darstellung der Schneideinrichtung 1 nach den Figuren 1 bis 3 stark vergrößert dargestellt wurde, ist auch die Eindringtiefe der Zähne 8, 9 an der Hautoberfläche 24 bzw. 29 stark vergrößert dargestellt. Bei der Schneideinrichtung 1 nach den Figuren 1 bis 3 wird vorzugsweise das Untermesser 3 oszillierend angetrieben. Es kann aber auch nur das Obermesser 2 anstelle des Untermessers 3 angetrieben sein. Denkbar ist auch, daß beide Klingen 2, 3 oszillierend bewegt werden. Als weitere Variante ist auch möglich, daß eines der beiden Klingen 2 oder 3 angetrieben wird, während die andere Klinge schwingend im Gehäuse (nicht dargestellt) eines Rasierapparates gelagert ist, so daß gegensätzlich oszillierende Bewegungen die Schneidwirkung erhöhen können.Since the representation of the cutting device 1 has been shown greatly enlarged according to Figures 1 to 3, and the penetration depth of the teeth 8, 9 is shown on the skin surface 24 and 29 greatly enlarged. In the cutting device 1 according to Figures 1 to 3, preferably the lower blade 3 is driven to oscillate. But it can also be driven only the upper blade 2 instead of the lower blade 3. It is also conceivable that both blades 2, 3 are moved in an oscillating manner. As a further variant, it is also possible that one of the two blades 2 or 3 is driven, while the other blade is swinging in the housing (not shown) of a razor, so that oppositely oscillating movements can increase the cutting action.
Die in den Figuren 1 bis 3 dargestellte Schneideinrichtung 1 kann beispielsweise bei dem von der Anmelderin seit langem vertriebenen Rasierer "Braun Synchro" anstelle des dort vorhandenen Trimmers eingesetzt werden, wobei dann der Rasierer in Richtung C mit den Zahnspitzen 11 auf der Hautoberfläche 24 (Fig. 2) entlang geführt wird. Die Schneideinrichtung 1 kann aber auch als Mittelschneider, wie er beispielsweise in dem von der Anmelderin vertriebenen Rasierer "Braun 360° Complete" oder "Braun Pulsonic" verwendet wird, eingesetzt werden, wobei dann der Rasierer in Richtung B auf der Hautoberfläche 29 (Fig. 2) entlang geführt wird. Um in beiden Bewegungsrichtungen B1 , B2 mit dem Mittelschneider Haare zu schneiden, müßte lediglich eine zweite Zahnreihe (nicht dargestellt) auf der anderen Seite an der Kante 25 ausgebildet sein, wobei dann die Oberseite 21 und nicht mehr die Spitzen 10, 1 1 den Kontakt zur Hautoberfläche herstellen. Im letzteren Fall verläuft dann die Hautoberfläche 29 (Fig. 2) parallel zu den Zähnen 8, 9 und die Endabschnitte 18 der Vorsprünge 17 gleiten auf der Haut und richten die an der Hautoberfläche 24 anliegenden Haare (nicht dargestellt) durch die oszillierende Bewegung der Spitzen 11 auf und führen sie den Zahnlücken 25, 26 der oberen und unteren Klinge 2, 3 zu.The cutting device 1 shown in FIGS. 1 to 3 can be used, for example, in the razor "Braun Synchro", which has long been marketed by the applicant, instead of the trimmer provided there, in which case the razor moves in the direction C with the tooth tips 11 on the skin surface 24 (FIG 2) is guided along. However, the cutting device 1 can also be used as a central cutter, as it is for example in that of the Applicant used razor "Brown 360 ° Complete" or "Braun Pulsonic" are used, in which case the razor is guided in the direction B on the skin surface 29 (Fig. 2) along. In order to cut hair in both directions of movement B1, B2 with the central cutter, only a second row of teeth (not shown) would have to be formed on the edge 25 on the other side, in which case the top 21 and not the tips 10, 11 would be the contact to the skin surface. In the latter case, the skin surface 29 (Figure 2) then extends parallel to the teeth 8, 9 and the end portions 18 of the projections 17 slide on the skin and direct the hairs (not shown) adjacent the skin surface 24 by the oscillating movement of the tips 11 and lead them to the tooth spaces 25, 26 of the upper and lower blades 2, 3 to.
Nachdem Haare in die zwischen den Zähnen 8, 9 gebildeten Schneidspalte 32 gelangen, werden sie an den von den Seitenflächen 33, 20 zu den Kontaktflächen 4, 5 begrenzende Schneidkanten 34, 35 bzw. den Kanten 30, 31 erfaßt und bei weiterer Verengung des Schneidspaltes 32 von den Schneidkanten 34, 35 abgeschnitten. Durch die vorgelagerten Vorsprünge 17 können die Zähne 8, besonders scharfe Seitenkanten 30, 31 am Übergang der Seitenflächen 20 zu der Oberseite 21 bzw. zu der Kontaktfläche 4 aufweisen, was auch dann auf die Spitzen 10 der oberen Klinge 2 als Kamm zutrifft. Dadurch erfolgt eine bessere Einfädelung der Haare in den Kamm und verbessert so das Rasierergebnis. After hair enters the cutting gaps 32 formed between the teeth 8, 9, they are detected at the cutting edges 34, 35 or the edges 30, 31 delimiting the contact surfaces 4, 5 from the side surfaces 33, 20 and at a further narrowing of the cutting gap 32 cut from the cutting edges 34, 35. By the protrusions 17, the teeth 8, particularly sharp side edges 30, 31 at the junction of the side surfaces 20 to the top 21 and the contact surface 4 have, which also applies to the tips 10 of the upper blade 2 as a comb. This results in a better threading of the hair in the comb, thus improving the shaving result.
